Enterprises are increasingly migrating to IP based communications technology to facilitate the new ways in which their customers and employees communicate in the digital world.

Connect your existing PBX to our best of breed equipment and use Stem Connect as your VoIP supplier for an enhanced user experience.

Session border controllers (SBCs) work behind the scenes to ensure that voice, video and data communications flow smoothly and securely between networks and the people who use them. An SBC is part firewall, protecting the network from IP-based attacks; part traffic cop, policing traffic to prevent overloads and directing it over shorter distances to save money; and part peacemaker, ensuring that networked devices from different vendors all speak the same language.
